What is Allegra

Allegra is a prescription drug classified as an antihistamine, and is used to block histamine in the body. Histamine is the cause of many symptoms associated with allergic reaction, including itchy eyes, sneezing, and runny nose.

How is Allegra Used

Allegra is used to treat symptoms that are associated with seasonal and year-round allergies, and is approved for use by ages 6 and older. It can also be used to successfully treat hives and itchy skin associated with skin allergies. Allegra works by simply by blocking the histamine, ultimately decreasing the symptoms, usually within one to three hours.

Taking Allegra

You should only take Allegra if the medication has been prescribed for you by a physician. You should always follow the directions on your prescriptions label. Allegra is usually prescribed for people suffering from seasonal allergies, year-round allergies, and skin allergies. It is taken by mouth, usually once or twice a day. These tablets work best when taken with a full glass of water and on an empty stomach. For optimal effects, Allegra should be taken on a regular schedule. If you miss a dose, you should take the medication as soon as you remember. However, if it is close to time for your next dose you should just skip the dose.
